Thm 3.9
Theorm 3.9 states that : two lines are perpendicular, then they intersect to form right angles.
These lines intersect and form four right
angles. They are perpendicularlines.

Thm 3.8 MEGHAN LEWIS AND ELENA FLORES If two lines intersect to form a linear pair, of congruent angles then the lines are perpendicular.
If the two intersecting lines have two congruent right angles forming a linear pair (which they do it is just not labeled) then lines A and B are perpendicular. THM 3.10 BY KAITLYN FIOLA IF TWO SIDES OF TWO ADJACENT ACUTE ANGLES ARE PERPENDICULAR THEN THE ANGLES ARE COMPLEMENTARY.
if line AB and line CB are perpendicular, then ABD and DBC are complementary.
